NightWatch® Deadbolt Technology

The Master Lock NightWatch® deadbolt is the only deadbolt that prevents an intruder from entering your home, even if they have your key. When the NightWatch feature is engaged, the lock cannot be opened from the outside, even with a duplicate key.

Two-thirds of U.S. homeowners have unknowingly exposed themselves to the risk of an intruder entering their home with a copy of their key. Every time a homeowner lends a key to a contractor or babysitter, or uses valet parking at a restaurant or hotel, there is a chance that their key could be duplicated & circulated without their knowledge.

NightWatch deadbolts were specifically created by Master Lock Company to prevent an intruder from entering even if they have a copy of the homeowner's key. It installs and functions like a standard deadbolt but once the feature is activated, all keys are blocked from unlocking the deadbolt.
